Roberto Rossellini, Carlo Lizzani's documentary about the influential Italian director, features archive interviews with Rossellini, François Truffaut, and Federico Fellini. Martin Scorsese discusses Rossellini's influence on his own work, as he did in
My Voyage To Italy. Lizzani (who contributed to the documentary
Il Etait Une Fois...) gives quite a dry commentary, though he does reveal a surprising detail: that he met with Marlene Dietrich as background research for Rossellini's film Germany Year Zero.
